Taipei 101, the world’s tallest green build­ing

Taipei 101 build­ing in Tai­wan has achieved a 10 per cent sav­ing in electricity us­age, water con­sump­tion and waste over the past two years. Its en­ergy con­sump­tion is 30 per cent more ef­fi­cient than an av­er­age build­ing. All of this re­sults in ap­prox­i­mately $700,000 of sav­ings in an­nual en­ergy costs.

The build­ing has a fully in­te­grated en­ergy man­age­ment and con­trol sys­tem in­stalled. In­tel­li­gent con­nec­tiv­ity en­ables the in­te­gra­tion of power mon­i­tor­ing, gen­er­a­tor man­age­ment, chiller con­trol, light­ing con­trol, zone pump vari­able- speed drive se­cu­rity man­age­ment, fire alarm sys­tems and car park­ing man­age­ment. Time con­trols have been placed on ex­trac­tor fans that pre­vi­ously ran con­tin­u­ously. Ev­ery ther­mo­stat and vari­able air vol­ume box was placed af­ter iden­ti­fy­ing a lo­ca­tion for it.

The en­ergy mon­i­tor­ing and con­trol sys­tem by Siemens stream­lines the op­er­a­tion and con­trol of the HVAC equip­ment through­out the com­plex, op­ti­mis­ing the en­tire en­ergy us­age. The ef­fi­ciency of the cool­ing sys­tem has been in­creased by ap­ply­ing im­proved al­go­rithms for the chiller plant and chang­ing the se­quence of op­er­a­tion.
